where
\(k= \varepsilon C_{2}/C_{1}.\) 
Hence \(\Theta (\tilde{W})\subset \mathfrak {L}_{\gamma }(\theta ),\,\gamma =C_{2}(1-\varepsilon )/C_{0}.\)  Thus, the claim of Lemma 1 [1]} is true regarding the operator \(\tilde{W}.\)  Using this fact, we conclude that the claim of Lemma 2 [1]} is true regarding the operator \(\tilde{W}\)  i.e. \(\tilde{W}\)  is m-accretive.
